The Ross-Tech VCDS (VAG-COM Diagnostic System) is a crucial tool for diagnosing and troubleshooting issues in Volkswagen, Audi, Seat, and Skoda vehicles. One common interface is the HEX-CAN USB, but understanding its limitations and the available upgrades is important. This article explores the differences between older HEX-CAN interfaces and the newer options, focusing on the capabilities of the current generation Ross-Tech VCDS tools.
The Evolution of Ross-Tech Interfaces: From HEX+CAN to HEX-V2
Older generation interfaces, like the HEX+CAN, rely on older technology. While functional for many older vehicles, these interfaces face limitations with newer models (2016 and later) due to evolving communication protocols within the cars. Ross-Tech addressed this with the introduction of the HEX-V2 and HEX-NET interfaces.
The HEX-V2 and HEX-NET share a powerful 32-bit microcontroller, significantly boosting communication speed, especially in CAN-based cars. This translates to faster diagnostics and more efficient data retrieval. For older K-Line based vehicles, the speed difference is minimal as the limiting factor is the module within the car itself.
Why Upgrade to a Newer Ross-Tech Interface?
The primary reason to upgrade from a HEX+CAN to a HEX-V2 is future compatibility. Ross-Tech has indicated that older generation interfaces will eventually lose official software support. While legacy software versions will likely remain available, they won’t include the latest features, updates, or support for newer vehicle models. Upgrading ensures access to ongoing improvements and compatibility with the latest vehicles.
HEX-V2 vs. HEX-NET: Choosing the Right Interface
Both the HEX-V2 and HEX-NET offer significant advantages over the HEX+CAN. The key differentiator lies in wireless functionality and onboard storage. The HEX-NET boasts built-in Wi-Fi and onboard storage, enabling wireless diagnostics through VCDS-Mobile. This allows users to perform diagnostics using smartphones, tablets, and laptops with a web browser, providing greater flexibility. The HEX-V2, on the other hand, provides a reliable wired connection via USB.
Making the Informed Decision
Choosing the right Ross-Tech VCDS interface depends on individual needs. If wireless functionality and mobile diagnostics are paramount, the HEX-NET is the ideal choice. For users prioritizing a dependable wired connection and not requiring mobile access, the HEX-V2 offers a robust and cost-effective solution. Both ensure compatibility with current and future vehicle models, offering the comprehensive diagnostic capabilities expected from Ross-Tech.
